Patent GB-195072-A (GB)
Abstract: 195,072. Shiptey, B. M. Dec. 16, 1921, [Convention date]. Paper-feeding arrangements.-In machines in which two printings are made on an inserted slip, means are provided which hold the slip from moving while the impression is being made and which feed the slip between the impressions; the invention being shown as applied to the machines described in Specifications 8119/15, [Class 106 (i), Calculating &c.], 100,568, 100,569 and 100,570, [both in Class 106 (i), Calculating &c.]; and as co-operating with printing mechanism as described in Specification 190,433 and slip-severing and retaining means as described in Specification 195,073, [Class 106 (i), Calculating &c. J. The slip is fed between type wheels 228, Fig. 4, and platens 466 and is held during each impression by two coaxial knurled rollers 508, 509 co-operating with a roller 510. The rollers 508, 509 are rotatably carried by an arm 507, Fig. 2, loose on a shaft 448, and the other end 511 being bifurcated to surround a pin 512 on a bell-crank 513. 515 loose on a shaft 461. A spring 519 surrounds a pin 516 on the arm 515 and a similar pin 517 on a lever 518 loose on the shaft 461 and carrying a roller 520 operated by the cam 522. Upon rotation of this cam 522 the arm 518 is rocked anticlockwise, Fig. 2, compressing spring 510 and rotating bell-crank 513, 515 anticlockwise; the pin 512 then moving the arm 507 clockwise so that the rollers 508, 509 are raised to grip the inserted slip. Later, when the cam 522 rotates the arm 518 clockwise, a pin 5518 on this arm strikes a shoulder 5515 on the arm 515 so that the parts ae positively returned to normal position. The ollowing mechanism feeds the slip between impressions ; a casting 523 loose on the shaft 506 is connected through links 524, 525 to an arm 526 fixed to a sleeve 527 rigid on the shaft 461, Eg. 4. The pin 528 connecting links 524, 525 moves in a slot 529 in a lever 530 which is bose on shaft 461 and is pivoted to an arm 31 of pitman 505 controlled bv cam 309. Anti-clockwise movement of this cam 309 moves pitman 505 to the right, as shown in Fig. 4, thus moving the pin 528 and arm 524 to the right, so that casting 523 is moved anti-clockwise, as shown in Fig. 4, or clockwise, as shown in Fig. 2. A roller 539 on lever 507 then wedges between the inner rim of roller 508 and a cut-away part 538 of lever 507 so that the roller 508 does not rotate. This occurs just as the roller 508 is raised to grip the slip as above described. The cam 309 next reverses the motion of the pitman 505 and arm 524, whereupon a roller 535 on the casting 523 becomes wedged between the inner rim of roller 508 and a cut-away part 537 of this casting 523 so that this casting is rotated anti-clockwise, as shown in Fig. 2, to feed the slip into the machine. The amount of this feed may be regulated by slackening and moving a screw 542, Fig. 1, in a slot 541 of a plate 540 on the sleeve 527, this screw 542 normally holding the arm 526 immovable during operation of the machine. When no slip is to be printed, an " On " and " Off " knob 660, Fig. 1, rigid with a sector 661, Fig. 2, is turned so that the sector 661 engages the end 662 of a pitman 663 pivoted to the arm 515 so that the latter cannot rotate anti-clockwise as shown in Fig. 2, to raise the roller 508.
